Fluorine Extration Process

How Does FEP Work?


FEP is a patented technology that extracts fluorine from uranium tetrafluoride (UF4) by heating a mixture of UF4 and metal oxide.  The metal oxide then combines with the fluorine and results in the production of specialty, high-value fluoride gas.  These high-purity fluoride gases are in ever-increasing demand for ion-implantation or chemical vapor deposition processes for microelectronics components and high-speed silicon chip manufacture. The uranium from the UF4 is converted into uranium oxide which is chemically stable and can be safely stored or disposed.
